Remarks. The population from Nosy Ankao is quite distant from the known area of distribution of the species (Wesener & Enghoff 2009). The colour and ring number (45) fit very well to the original description. Like the specimens from Nosy Be, the ones from Nosy Ankao are smaller than those from Ankarana (42 versus 32 mm in male length, 3.2 versus 2.6 mm in width). The anterior and posterior telopods, as well as the colour patter and the male anterior legs fit also to S. univirgatus . We successfully barcoded the Nosy Ankao population of S. univirgatus , but a comparison is difficult. Only sequences of two other Spiromimus species are available: S. scapularis Wesener & Enghoff 2009 from the NW Forêt de Binara and S. triaureus Wesener & Enghoff, 2009 from the western dry forests.
